PROBLEM TO BE SOLVED: To provide a producible dicing/die bonding integrated tape having high stickiness in the dicing process, and having low stickiness in the pickup process, especially a dicing/die bonding integrated tape having an adhesive layer capable of expressing low stickiness in the pickup process.SOLUTION: In a dicing/die bonding integrated tape where at least a base material layer, an adhesive layer and an adhesion layer are laminated in this order, the dispersion component value Aispersion when dividing the surface free energies A, A of the adhesive layer before ultraviolet light irradiation into a polarity component and a dispersion component, and the surface free energies B of the adhesive layer after ultraviolet light irradiation satisfy the relation of following general formula (I). Aispersion/((B-A)/A)≤20...(I). |
